Agricultural product storage and preservation test chamber

Abstract

An agricultural product storage and preservation test chamber is composed of a chamber body, a chamber door, an airflow guiding plate, a micro-circulation air curtain draught fan, a cold accumulation and conduction plate layer, temperature sensors, a control electric appliance and a goods shelf partition layer, wherein the chamber body can be totally sealed and is made of transparent hollow plastic plates; the cold accumulation and conduction plate layer is composed of a cold conduction plate and a cold conduction groove which are made of metal material with heat conduction coefficient, and cold accumulation refrigerant material is injected into the cold conduction groove; the airflow guiding plate is parallel to the cold conduction plate, and the airflow guiding plate is connected with the left wall and the right wall of the chamber body in a welded mode and not connected with the bottom wall of the chamber body; the connection corner between the inner top wall of the chamber body and the cold accumulation and conduction plate is provided with the micro-circulation air curtain draught fan; the temperature sensors are installed inside and outside the chamber body respectively; an air inlet hole, a valve, an air outlet hole and a valve are welded to the bottom wall of the chamber body; the goods shelf partition layer is arranged in the chamber body. The agricultural product storage and preservation test chamber is not provided with a refrigerating unit, cooling capacity needed for chamber body test products is provided by the cold accumulation and conduction plate, the temperature of the test products is kept, and the uniformity of temperature in the chamber is obviously improved.

Description

technical field [0001] The patent belongs to storage and transportation fresh-keeping equipment for agricultural products, in particular to a fresh-keeping box for carrying out storage and fresh-keeping experiments on fruits of agricultural products. Background technique [0002] According to data, the loss rate of fruit and vegetable products in my country is 20%~35% in the process of post-harvest storage, transportation and preservation, and the loss rate of grain is about 8%, which is different from the loss rate of post-harvest agricultural products in developed countries. Far, the losses caused are astonishing. It can be seen that there is still a large gap in the research and application of corresponding technologies in my country in the storage, transportation and processing of agricultural products after production. Carrying out such research has very important practical significance. [0003] The post-harvest fruits of agricultural products are substances with the ch...

AI Technical Summary

Problems solved by technology

Since the above test chamber is equipped with a refrigeration evaporator, the temperature of the chamber will drop or rise rapidly, and the exposed agricultural product test materials in the chamber will increase the water loss rate due to large temperature fluctuations.
